I don't think airlines consider it as a disadvantage, because it seems you've got a reasonable explanation. Besides, flying is mostly considered as a passion. People won't compare it as the doctor with a PhD who likes to be a nurse or something, I think.
For myself: I'm a legal cousel with a masters degree. In the interviews I did for flight schools and the British Airways programme, the interviewers did realize that flying is my passion and never wondered themself about the radical switch I'm busy with.
